Ngokuthuthukiswa kwamanethiwekhi okuxhumana abheke ku-broadband kanye nokuhamba, i-optical fibre wireless communication system (ROF) ihlanganisa ukuxhumana kwe-fiber optical kanye nokuxhumana okungenantambo, inikeze ukudlala okugcwele kuzinzuzo ze-broadband kanye nokuphikisana nokuphazanyiswa kwemigqa ye-fiber optical, njenge ...

Iswishi ye-PoE iswishi esekela ukunikezwa kwamandla kukhebuli yenethiwekhi. Uma kuqhathaniswa neswishi evamile, itheminali yokwamukela amandla (njenge-AP, ikhamera yedijithali, njll.) ayidingi ukuxhunywa ngentambo ukuze kunikezwe amandla, futhi ukwethembeka kwayo yonke inethiwekhi kuphakeme. Ukubuka konke kwe-Power Over Et...

1. Uhlolojikelele I-inthanethi Yezinto ihlomisa izinzwa ezintweni zangempela ezihlukahlukene ezifana namagridi kagesi, imizila yezitimela, amabhuloho, amahubhe, imigwaqo emikhulu, izakhiwo, amasistimu okuphakelwa kwamanzi, amadamu, amapayipi kawoyela negesi, nezinto zikagesi zasendlini, futhi ixhume nge-inthanethi, bese uqhuba izinhlelo ezithile ukuze ufeze...

1. Isingeniso senethiwekhi ye-EPON I-EPON (i-Ethernet Passive Optical Network) iwubuchwepheshe benethiwekhi yokufinyelela i-fiber optical evelayo, esebenzisa isakhiwo se-point-to-multipoint, imodi yokudlulisa i-fiber optical passive, esekelwe kuplathifomu ye-Ethernet enesivinini esikhulu kanye ne-TDM yesigaba sokuhlukanisa isikhathi se-MAC (MediaAccessControl ) mina...

1.indlela yokufaka Kungakhathaliseki ukuthi ingaphakathi endlini noma ngaphandle, kufanele uthathe izinyathelo zokulwa ne-static uma usebenzisa imojula ye-optical, futhi uqinisekise ukuthi uthinta imojuli ye-optical ngezandla zakho ngenkathi ugqoke amagilavu ​​aphikisana ne-static noma ibhande lesihlakala eliphikisana ne-static. Kwenqatshelwe ngokuphelele ukuthinta i-golden fing...

Esikhathini sanamuhla se-inthanethi, kokubili ukuthunyelwa kwenethiwekhi yebhizinisi nokwakhiwa kwesikhungo sedatha akukwazi ukwenza ngaphandle kwamamojula abonakalayo nokushintsha. Amamojula we-Optical asetshenziswa kakhulu ukuguqula amasignali kagesi ne-optical, kuyilapho amaswishi asetshenziselwa ukudlulisa amasignali e-photoelectric. Phakathi kwe-optica eminingi ...
